I don't get how cats can get fat at all, unless they are house cats (which I disagree with the notion of keeping a cat in the house 24 hours a day, poor thing!). Even then, they shouldn't be fed so much food as to get as overweight as those two cats.
It's goddamn murder. I'm sorry but anyone who let's their pet get THAT fat shouldn't be allowed to own one. The least she can do is come to terms with her failure. Nope, it must be hereditary. Bull...shiiiiiiiit.
